Solar Charging and Amp Hours
Is the amperage from a solar panel constant as the battery it is charging charges up? I.e., as your battery reaches full charge, the current drops to zero either via the charge controller or the eq...

The controller does not gradually limit the current to the battery. The battery is the one doing the limiting as amps taper.
One way the controller does limit amps to the battery is suddenly, not gradually, if it drops voltage from 14.x to 13.x as part of its programmed charging profile. The battery will then accept fewer amps at that lower voltage at the same SOC.
Another way is at first during Bulk, the controller (if an MPPT type) will "clip the amps" to ensure it does not over-heat by going over its output amps rating.
